To aZZ lwhom t may concern:

. Be it known that ll, HENRY Bauman, a subject of the King of Great Britain and lreland, residing at Hi her Tranmere, Birkenhead, Cheshire, Eng and, have invented certain new and useful improvements in Air Valves for internal-Combustion Engines; and l do declare the following to bea full, clear, and enact description of the invention, such as will enable others skilled in the -art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters and figures part of this specification.

This invention relates. to a new or improved valve for automatically supplying extra air to internal combustion engines and has for its primary objects the economy of fuel and improving the running ol the enine. umber of tests on the roadiwith various road vehicles propelled by internal combustion engines and using petrol as a iluel that the device effects an increase of about 25% of reference marked thereon, which form a ot rnilage per gallon of fuel besides iin-l proving the running ot the engine at all speeds. i Y

The present invention relates to that type of ball valve for admitting auxiliary air to internal combustion engines in which a valve' body adapted to be attached tothe induction ipe or manifoldis provided with an air in- .et and outlet for admitting and discharging atmos heric air. llie ball valve is coniral compression spring which trolle by a s l is regulated y a member screwing intov the casing to press the ball on its seating andis provided with means for locking the reguating member lwhen. adjusted.

'llhe present invention which obviates certain defects in practice with valves of the part formed with a cover at its lower end which is drilled with' a seriesl of holes: :lor the admission of air7 a coned valve seating of an appreciable depth carried within the cylindrical body-part at some distance above the lower end thereolha ball valve contactt ing with said seating ot such a diameter that its lower portion projects beneath its seating, an internal screw thread formed in the upper portion ont the valve body, 'and exteriorly screw threaded plug screwing into said valve body and axially bored with the upperv end lt has been shown by a considerable.

'its length to yforni a a cylindrical body two diameters, a reduced part or spigot on of said plug adapted; to screw into the induction pipe or manifold, means for allowing the plug to be adjusted with respect to the valve body, a lock nut engaging both the screwed plug and the upper end of the valve body and a spiral compression spring acting between the .ball valve and the shoulder formed the plug by the difering thereof.

This invention will be now more particularly described making reference to the accompanying drawing in whichlligure l is a view in side elevation of an extra air valve embodying the present ininternal diameters vention.

Figure 2 is a view in Figure 3 is a view in and Figure el is an underside plan view.l Throughout the views similar parts are marlred with lilre letters of reference. d cylinder a has its lower end closed by a plate or' formed with a cover al in whic is drilled a series of holes lag for the admission or ain. J ,dt perforations or holes a is fixed or lormed a coned seating as oit an appreciable depth for a ball `valve which is ot vsuch a diameter that it rejects beneath the seating, as shownu e upper portion et the cylinder-r 1s internallyscrew threaded to receive an eirteriorly screw threaded plug c which is formed at its upper end with a reduced part or s igot c1.V l i Cl is spigot c1 plan thereoit.

some. distance above the Sli liti

is exteriorly screwlthreaded l i pipe or manifold of the en gine. The plug c is bored with twodiaineters c2, 40* through ce passage .for the air to pipe or manifold. The shoulder formed between the bore c2 and y the bore cS forms a bearing for the upper end of a helical spring d, thelower end et vwhich ini inges on the ball t. By screwing the plug, y means or dats c4Z thereon, into or out of the cylinder a, provision is made for varying or adjustingr the strength of the s ring d. A loclr nut e is provided on the p ug c tovengage the upper edge of the the induction Mld cylinder a to loclr the plug in position sitter adjustmentx rllhe lower edge ofthe cylinder a may be provided with a hexagonal or a lrnurledl bead or dange at adapting the ting to he screwed into the induction pipe or manifold.

In some cases wire gauze may be placed over the perforations or holes a2 to prevent entry of foreign matter with the sucked in air.

Having 'now particularly described and ascertained the nature of my saidV invention and in what manner the same is to be performed, I declare that what I claim is An air supply valve for internal combustion engines, comprising a hollow val\'c body portion 'formed with an internal valveseat spaced a distance from the adjacent end of the body portion, a closure-cap extending partially up into the space beneath the valve seat and formed with borings to formI in conjunction with the space between the cap and valve-seat an air cushion for thevalve,

a ball-valve resting on the valve seat and In testimony whereof I atix my signature.

HENRY BARKER.
